Tru ball fang 4, just bought it today. Crisp at release and no pinch on the loop off the string. I also have 2 other thumb releases that I use, I think that they are also tru ball thumb releases. When practicing, I will put all three in my pocket or pouch and after each shot, I will change releases. each release has a different point of pressure to make the release fire, in return cause me to concentrate on my target and not the release. This practice and long range practice has helped me improve so much.
After all that, I refer the thumb type releases.
